' LOOSE-LEAF CONNECTION.

Application filed June 1, 1922. Serial No. 565,042

To all whom it may concern:

Be it known that I, FRANoIs L. MARTIN, a citizen of Poland, and a resident of the city of New York, borough of Brooklyn, in the a county of Kings and State of New York,

have invented .a new and Improved Loose- Leaf Connection, of which the following is a full, clear, and exact description.

This invention has relation to loose leaf to binders and has particular reference to the means of connecting the leaves to the binder.

The invention contemplates as its primary object a loose leaf connection for detachably associating the leaves of pages to the binder which eliminates the necessity of employing bolts, split rings, or other standard forms of separable fastening elements for this purpose.

As a further object the invention contemplates a loose leaf connection in which resilient clips carried by the leaves are associated with or disassociated from complementary members carried by the binder by snapping the same into and out of engagement therewith.

As a further object the invention aims to produce an extremely simple and inexpensive loose leaf connection which affords an expeditious means for attaching or detaching the leaves to the binder.

With the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawing'it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed. I

In the drawing Figure 1 is a perspective view of a loose leaf binder illustrating the improved means of connecting the leaves thereto.

Fig. 2 is a fragmentary end view thereof.

Fig. 3 is a fragmentary side view thereof.

Referring to the drawings by characters of reference, the binder embodies a back 10 to which the covers 11 and 12 are hingedly or flexibly connected for folding into book form. Transversely disposed bars 13 are connected in longitudinally spaced relation and project from the inner face of the back 10. The bars 13 are preferably provided with downwardly and inwardly curved extremities 14 which are formed into eyes 15 through which rivets or other securing elements 16 are passed and anchored to the back 10. Each leaf 17 which is adapted to be detachably associated with the binder has connected to its rear inner edge a plurality of longitudinally spaced clips 18 correspond-- ing in number and spacing to the bars 13.

The clips are preferably constructed from av single length of resilient wire which is bent medially into an elongated looped form 19 with the terminals 20 thereof in abutting relation. The terminals are then provided with outwardly divergent portions 21 and with inwardly coiled extremities 22 which are designed to coact with each other to embrace the bar 13 for detachably and shift ably associating the leaf 17 therewith. The means for attaching the clips 18 to the rear edge of the page preferably consists of a substantially U-shaped tab 23, the inner faces of the arms 24 of which are gummed to adhere to the opposite surfaces of the page orleaf 17. The bight 25 is received by the loop 19 of the clip whereby the leaf is independently hinged to the clip for turning movement. In applying the leaves 17 to the binder, the coiled portions 22 of each clip affords an entering mouth of gradually decreasing width and said portions are sprung apart when forced over the bar and snapped in place over the same to fric- I tionally retain the clip in associated relation with the bar. To remove the page or leaf 17, the same is grasped and pulled outwardly to spring the coiled portions 22 apart. The inner terminals of the coils afford a similarly formed exit mouth of gradually decreasing widths which facilitates the removal or displacement of the clip from the bar 13.

The inwardly curved extremities 14 of the bars constitute a guide for the clips whereby the pages and clips may be turned to a position parallel with the covers 11 and 12 when the binder is laid flat as illustrated in Fig. 2. The operations of attaching and removing the leaves is greatly facilitated by the form of connection and it is thought to be a decided improvement over the present means of connection now in general use. The clips together'with the attaching tabs 23 may be associated with pages or documents of various sizes in order that the binder may be universallyemployed for the filing ofvarious papers and instruments.

laclaim: 1. In a loose leaf binder, the combination with a binder back provided with transverse bars, of clips adapted to be attached to the leaves and resiliently engaged with the bar, said clips each comprising a single strip of resilient Wire bent to provide a medial loop with the terminals thereof in abutting relation and provided with outwardly divergent portions having inwardly coiled extremities adapted to embrace the bar for detachable and shiftable association therewith.

I 2. In a loose leai binder, the combination with a binder back provided with transverse bars, .ofclipsadapted to ,beattached to the leaves-and resiliently engaged with the bar, said'clips each comprising a single stripof resilient Wire bent to provide a medial loop with the terminals thereof in abutting relation and provided with outwardly divergent portions having inwardly coiled extremities adapted to embrace the bar for detachable and shiftable association therewith, said clips being associated. With the leaves by means of gumined tabs passed through the medial loop of the clip with the opposite separable clamping members. adapted to embrace the bar, and ineansby which each of the loops is carried consistingot'a folded strip, theconironting faces of which are provided with anadhesive forattaching the same to a sheet or leafto be associated with the binder.
